CUTTING .AND GRINDING APPARATUS.

To aZZ 'whom it may concern:

Be it known that I, PURoHEs MILES, of New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Implement or Device for Cutting Meat and Grinding Coee and other Substances; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specication, in which- Figure l, is an end view of my invention. Fig. 2, a longitudinal vertical section of the same taken in the line w, m, Fig. 1. Fig. 3, a detached plan of the shell in an open state. Fig. 4, a transverse section of my improvement taken in the line y, y, Fig. 2. Fig. 5, an end view of the smaller end of the shell showing the disk tted therein.

Similar letters of reference indicate corresponding parts in the several figures.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents a conical shell which is formed of two equal longitudinal parts connected at one side by joints or hinges a, a, and supported horizontally at a suitable height by feet Z). The shell A at its upper part and larger end has an opening c, through which the meat to be cut or substance to be ground is fed into the shell. The smaller end CZ, of the shell is open and forms the discharge aperture.

Within the shell Athere are spiral grooves e, which are formed by projections f, cast with the shell. The grooves c, gradually decrease in dimensions both in width and depth from the larger toward the smaller end of the shell. The grooves c, are at the larger end of the shell and ext-end about half its length, the other and smaller part of the shell is provided with longitudinal grooves g, which are formed by projections Zz., cast with the shell. The grooves g, also gradually diminish in dimensions from their inner to their outer ends, but they do not extend quite to the end of the shell, as will be seen by referring to Figs. 2 and 4.

Within the shell A, there is placed a rotary cutter head B. This head is of cylindrical or an approximate form, and it has a series of spiral knives z', y', attached which knives gradually diminish in depth from the larger to the smaller end of the cutter head. ,l The knives z', extend the whole length of the cutter head, but the knives j, extend over the longitudinal grooves g, only as shown in Fig. Q-the knives j, being between the knives z'.

At the outer end of the cutter head B, there is secured by a screw 7c, a disk C, which has two cutting projections Z, Z, with points m, m, which iit in grooves n, n, in the shell and keep the disk C, stationary as will be fully understood by referring to Figs. 2 and 5.

The cutter head B, has a journal o, at one end, and this journal rests in a bearing p, at the larger end of the shell A, the opposite end of the cutter head simply rests in the smaller end of the shell. The journal 0, has a crank D, on its outer end.

The operation is as follows-The crank D, is turned and the meat to be out or article to be ground is passed into the shell A, through the opening c. The grooves e,

serve chieily as feeders and in connection j with the knives z', slightly cut, and at the same time force the substance' operated upon toward the grooves g, the projections ZL, of which serve as bearings while the knives act upon the substance and reduce it to the required iineness by a cutting operation. The gradually diminishing dimensions of the grooves y, prevent a too rapid discharge of the cut or ground substance, the latter being forced out from the machine by the rotation of the knives z', in connection with the spiral grooves c. The cutters Z, Z, on the stationary disk C, cut any strings or long fibers which may connect pieces of meat as the latter is forced from the shell. The cutters thus insure a proper discharge of the cut meat, and in case of grinding coffee or other substance the too rapid discharge of the substance to be ground is prevented by the disk C, which may have two or more projections ax in addition to the cutters Z, Z, to obstruct the discharge end of the shell A,

see Fig. 5. Several disks C, may be url grooves e, and longitudinal grooves L of the nished with each device having a different concave A in the manner and for the pur- 10 d, number of projections a* and cutters Z Z. poses herein shown and described.

Having thus described my invention 5 what I claim as new, and desire to secure PURCHES MILES by Letters Patent, is VWitnesses:

The combination of the spira-l knives z', j BENJ. E. BEECHER, i and rotary cutter head B, with the spiral B. JACOGKS.
